Ah duh, I should have just read the additional docs portion. A comment here
reminding users to checkout the additional details would suffice
> Create a processor to validate CSV against a user-supplied schema

> Key: NIFI-1942
> URL: https://issues.apache.org/jira/browse/NIFI-1942
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Minor
> Fix For: 1.0.0
>
>
> In order to extend the set of "quality control" processors, it would be
> interesting to have a processor validating CSV formatted flow files against a
> user-specified schema.
> Flow file validated against schema would be routed to "valid" relationship
> although flow file not validated against schema would be routed to "invalid"
> relationship.
